DESCRIPTIONS OF SOME NEW GENERA OF AUSTRALIAN HETEROMEROUS 
BEETLES IN THE COLLECTION OF THE REY. F. W. HOPE. 
CYPHALEUS, Hope . 
Corpus oblongo-ovatum, elytris convexis rugosis lateribus parallels. Caput 
mediocre, clypeo ante oculos utrinque prominente, basin antennarum tamen vix 
obtegente. Antenna) longitudine capitis cum dimidio thoracis, articulis apicalibus 
parum crassioribus et brevioribus. Mandibul® subtrigonee, externe rotundat®, 
apice bifid®, intus membrana in cavitate recepta, in struct®. Maxillae lobo interno 
in hamum corneum acutum producto, lobo externo magno inermi setoso. Palpi 
max. articulo ultimo magno securiformi. Men turn subquadratum, antice latius 
angulis antice rotundatis: labium subquadratum angulis etiam rotundatis. Palpi 
lab. breves, in scapos parvos insidentes, articulo 3tio subsecuriformi. Protliorax 
postice latior, angulis acutis. Elytra magna, prothorace multo latiora, convexa, 
valde punctato-rugosa. Pedes longi simplices. 
Species I. Cyphaleus formosus , Hope. Niger, nigro-setosus, supra punctatus, elytroruru 
dimidio basali viridi, purpureo cincto,apico violaceo-nigricante, punctis elytrorum majori- 
bus, et Bacpe conflncntibus. 
Long. corp. lin. 11^. 
Obs .—The splendid purple oval edging to the green base of the 
elytra is a very peculiar character in this insect. 
Species II. Cyphaleus iopterus , Hope. Niger, nigro-setosus, supra punctatus, punctis 
elytrorum majoribus distinctis, apicem versus obliteratis ; elytris nitide violaceis. 
Long. corp. lin. 10. 
Obs .—The smaller size, more regular, and slighter punctation of 
the elytra, which are smooth behind, and their uniform violet- 
purple colour, are the chief differences between the two preceding 
insects. 
Species III. Cyphaleus rugosus. Totus ater, elytris rugoso-punctatis. 
Helops ? rugosus, G. R. Gray, in Griffith, An. K. Ins. pi. 80, f. 5. 
Helops aterrirnus, G. R. Gray in ditto, pi. 74, fig. 5 (details), and Part 31, 
p. 22. 
Long. corp. lin. II. 
CHARTOPTERYX, Hope . 
Corpus ovatum convexum, antice attenuatum. Antennae capite cum thorace 
longiores, graeiles, articulis 4 apicalibus brevibus et vix crassioribus. Mandibulae 
crass®, apice acut®, curvatae, intus apicem bifid®, spatio marginis interni mem¬ 
brana repleto. Maxill® panrte, lobo interno apice liamo parvo acuto corneo inflexo 
armato. Palpi max. articulo ultimo securiformi, mentum subcordato-truncatum, 
labium integrum ciliatum. Palpi lab. breves, articulo ultimo sub-seeuriformi. Pro¬ 
thorax sub-planus postice latior, lateribus rectismarginatis, Elytra basi vix pronoto 
latiora, gradatim dilatata convexa, postice areolata,apice acuto. Pedes longi graeiles. 
Obs .—The generic name is proposed in allusion to the map-like
